Abstract: Objective To explore the prospects for applying a brain-computer interface system in the reha-bilitation of dyskinesia by testing the brain-electricity signals of spinal cord injury patients and stroke patients during motor imagery. Methods The brain-electricity signals of 5 healthy people, 4 spinal cord injury patients and 2 stroke patients were tested during motor imagery, and the results were analyzed with a computer. Results All of the 5 healthy people showed event-related synchronization and desynchronization (ERS/ERD) in the α and β bands in the motor related cortex. Three of the 4 spinal cord injury patents showed similar characteristics, and 1 showed ob-vious and stable characteristics, but the 2 stroke patients did not show meaningful characteristics. Conclusions Spinal cord injury patients have brain-electrlcity characteristics similar to those of healthy people when they are expe-riencing motor imagery, whilst in the affected hemisphere of stroke patients the brain-electricity characteristics are not similar to those of healthy people.
